RESUMEN

El paradigma de apoyos y el de calidad de vida se han transformado en guías fundamentales para los avances en el ámbito de la discapacidad intelectual (DI). Con base en una muestra de 93 personas adultas con DI, se analiza, desde un enfoque cuantitativo no experimental, la relación entre la calidad de vida y las necesidades de apoyo, aplicando la escala INICO-FEAPS y la escala de Intensidad de Apoyos (SIS) para cada constructo. Los principales resultados evidencian que existe una relación fuerte e indirecta entre calidad de vida y necesidades de apoyos, y también la relevancia de analizar dichos resultados desde variables como grado de discapacidad, sexo o nivel socioeconómico. La discusión permite inferir la necesidad de discutir nuevas estrategias en torno a categorías como el grado de discapacidad, la autodeterminación e inclusión social, como elementos facilitadores de la calidad de vida y apoyos desde un enfoque integral que contribuya al desarrollo de estrategias de programas sociales para la población con DI.

The support paradigm and the quality of life paradigm have become fundamental guides for progress in the field of Intellectual Disability (ID). Based on a sample of 93 adults with ID, the relationship between Quality of Life and Support Needs is analyzed from a non-experimental quantitative approach, applying the INICO-FEAPS scale and the SIS Support Intensity scale for each construct. The main results show that there is a strong and indirect relationship between quality of life and support needs, and the relevance of analyzing these results from variables such as the degree of disability, sex or socioeconomic level. The discussion allows us to infer the need to discuss new strategies around categories such as the degree of disability, self-determination and social inclusion, as facilitating elements of quality of life and supporting a comprehensive approach that contributes to the development of social program strategies for the population with ID.

RESUMEN

BACKGROUND: Chilean midwives have been identified as essential for successfully implementing an abortion law, a practice which could potentially be understood as contradicting their central mission. Nevertheless, to date, there has been no investigation into how Chilean midwives have incorporated induced abortion care provision into their professional identity. OBJECTIVE: To elucidate how Chilean midwives understand and provide abortion care and how they have (re)defined their professional identity to include induced abortion care. This article reports the findings of the second part of this aim. METHODS: This study was underpinned by a constructivist grounded theory methodology informed by a reproductive justice and feminist perspective. Midwives from Chile who have cared for women undergoing abortion were invited to participate in the study. After purposive and theoretical sampling, fifteen midwives were recruited. FINDINGS: Midwives' identity is woman-centred, with high value placed on their role protecting life. These two aspects of midwives' identity are in contradiction when providing abortion care. Midwives' identity results from and informs midwives' practice. Midwifery regulation influences both practice and identity. The model 'Navigating a maze' explains the interaction of these three elements. CONCLUSION: Midwives' identity response to the enactment of the Chilean abortion law is an example of how professional identity must navigate regulation and practice to make sense of its purpose. In light of this study's findings, the current tension experienced in midwives' identity should be carefully attended to prevent adverse outcomes for midwives and the Chilean population.

RESUMEN

INTRODUCTION: In Chile, more than 70% of adults are infected by Helicobacter pylori. Clarithromycin should not be used in any regimen if there is >15% resistance to this antibiotic, being greater than 26% in our population. In this scenario, the effectiveness of triple therapy (proton pump inhibitor [PPI], clarithromycin, amoxicillin) was only 63.8%. AIM: To evaluate the eradication rate and safety of dual therapy (esomeprazole and amoxicillin) in high doses, through a prospective, observational, and descriptive study. METHODS: Patients with a positive urease test obtained in an upper digestive endoscopy were included. Any other previous H. pylori eradication regimen were excluded. All patients were treated with esomeprazole 40 mg three times a day and amoxicillin 750 mg four times a day for 14 days. The eradication rate of the dual therapy was evaluated with the H. pylori stool antigen test (the Pylori-Strip® test used) 6 weeks after completing the eradication treatment and with at least 14 days without PPI, being a negative result, confirmation of the effectiveness of this regimen. RESULTS: Of 122 patients, 106 had a negative H. pylori antigen in stool; The intention-to-treat and per protocol analysis, the eradication rates were 91.8% [95% CI: 87%-97%] and 94% [95% CI: 90%-98%], respectively. Four patients discontinued treatment due to adverse effects. Smoking and adherence to treatment were associated with eradication rate. CONCLUSIONS: In this cohort of patients with H. pylori infection, high-dose dual therapy has a high eradication rate and good adherence, raising the possibility that it could be used as first-line therapy in our country. Studies with a larger number of patients should confirm these results.

RESUMEN

There are various climate policies to decarbonize the energy matrix of a country. In the case of Chile, a carbon tax of 5 USD/tCO2 was initially implemented, and later, a schedule was established for the phase-out of coal-fired thermoelectric plants, all the above in the absence of subsidies for non-conventional renewable energy (NCRE). This study uses a computable general equilibrium (CGE) model and microsimulations to assess the contribution of current climate policies and other more demanding scenarios that accelerate the decarbonization of the Chilean energy matrix, considering economic, environmental, and distributional impacts. Specifically, carbon taxes are simulated with and without complementary climate policies (phase-out of coal-fired power plants and NCRE subsidies). The results show that the scenarios that combine the three climate policies generate a greater decrease in greenhouse gas emissions (40.4% âˆ¼ 57.5%). Besides, the drop in GDP is more pronounced when coal-fired thermoelectric plants phase out (0.3% additional), and NCRE subsidies contribute to moderately reducing emissions. However, NCRE subsidies reduce the negative effect on households' expenditure and income, especially in the poorest quintile. Finally, microsimulations show marginal changes in income distribution and an increase of up to 0.4 percentage points in the poverty rate.

RESUMEN

Soils in hyper-arid climates, such as the Chilean Atacama Desert, show indications of past and present forms of life despite extreme water limitations. We hypothesize that fog plays a key role in sustaining life. In particular, we assume that fog water is incorporated into soil nutrient cycles, with the inland limit of fog penetration corresponding to the threshold for biological cycling of soil phosphorus (P). We collected topsoil samples (0-10 cm) from each of 54 subsites, including sites in direct adjacency (<10 cm) and in 1 m distance to plants, along an aridity gradient across the Coastal Cordillera. Satellite-based fog detection revealed that Pacific fog penetrates up to 10 km inland, while inland sites at 10-23 km from the coast rely solely on sporadic rainfall for water supply. To assess biological P cycling we performed sequential P fractionation and determined oxygen isotope of HCl-extractable inorganic P δ 18 O HCl - P i $$ \mathrm{P}\ \left({\updelta}^{18}{\mathrm{O}}_{\mathrm{HCl}-{\mathrm{P}}_{\mathrm{i}}}\right) $$ . Total P (Pt ) concentration exponentially increased from 336 mg kg-1 to a maximum of 1021 mg kg-1 in inland areas ≥10 km. With increasing distance from the coast, soil δ 18 O HCl - P i $$ {\updelta}^{18}{\mathrm{O}}_{\mathrm{HCl}-{\mathrm{P}}_{\mathrm{i}}} $$ values declined exponentially from 16.6‰ to a constant 9.9‰ for locations ≥10 km inland. Biological cycling of HCl-Pi near the coast reached a maximum of 76%-100%, which could only be explained by the fact that fog water predominately drives biological P cycling. In inland regions, with minimal rainfall (<5 mm) as single water source, only 24 ± 14% of HCl-Pi was biologically cycled. We conclude that biological P cycling in the hyper-arid Atacama Desert is not exclusively but mainly mediated by fog, which thus controls apatite dissolution rates and related occurrence and spread of microbial life in this extreme environment.

RESUMEN

OBJECTIVE: To specifically examine the multiple factors related to the increase in depressive symptoms during the COVID-19 outbreak in older adults in Chile. METHOD: A longitudinal study was conducted using a dataset from a nationally representative survey cohort of Chilean older adults followed at three time points during the COVID-19 outbreak. The main outcome was depressive symptoms (Patient Health Questionnaire scale). The independent variables included: age, sex, educational level, geographic area, living alone, self-perceived health, self-reported resilience, loneliness, and social isolation. RESULTS: A total of 424 older adults were included. Female sex (ß = 0.95, 95% CI: 0.22 to 1.68) and loneliness (ß = 1.21, 95% CI: 1.05 to 1.37) were the main risk factors for an increase in depressive symptoms in older adults. In contrast, living outside the metropolitan region (ß=-0.70, 95% CI: -1.39 to -0.02), living in company (ß=-0.34, 95% CI:-1.24 to 0.56), having better self-perceived health (ß=-5.04, 95% CI:-6.33 to -3.75) and greater resilience (ß=-0.30, 95% CI: -0.38 to -0.23) were preventive factors. CONCLUSION: These results provide useful evidence to develop mental health prevention or control strategies for older adults. CLINICAL IMPLICATIONS: The findings highlight the importance of a holistic approach to health care for older adults that integrates strategies to address loneliness, foster resilience, and promote an active social life.

RESUMEN

Pain is a major public health concern associated with emotional disorders and physical disability and generates increased sick leave and healthcare expenditures. However, despite its social impact and the high pain-related costs, the training of healthcare professionals, such as physical therapists, in pain management is insufficient, leading to an inadequate therapeutic approach. This study aimed to determine the existence of a specific program on pain within the curricula of physical therapy careers in accredited universities in Chile. Out of 40 physical therapy careers, we analyzed 38 curricula. None of them had a specific discipline on pain management in their curricula. Although there is no concrete definition of the best modality for pain education in undergraduate students, it has been shown that following the International Association for The Study of Pain curricula improves students' knowledge and awareness of pain management.


El dolor es un importante problema de salud pública, asociado con trastornos emocionales y discapacidad física, generando un aumento en licencias laborales y gastos en el sistema de salud. Sin embargo, a pesar del impacto social y los altos costos relacionados con el dolor, hay una capacitación insuficiente en la formación de los profesionales de la salud, como kinesiólogos y fisioterapeutas sobre el manejo del dolor, lo que lleva a un abordaje terapéutico inadecuado. El objetivo de este estudio fue determinar la existencia de un programa específico en dolor dentro de las mallas curriculares de las carreras de kinesiología en universidades acreditadas en Chile. De 40 carreras de kinesiología, analizamos 38 mallas curriculares. Ninguna de ellas presentaba una disciplina específica sobre dolor en su plan de estudios. Si bien no hay una definición concreta sobre la mejor modalidad para la educación en dolor en alumnos de pregrado, se ha demostrado que seguir los planes de estudios de la impacta significativamente en el conocimiento y las creencias del dolor de los estudiantes.

RESUMEN

BACKGROUND: Antenatal micronutrient supplementation has been defined as a priority for Low-and Middle-income Countries (LMICs). However, it is also relevant to assess its performance in middle-high income countries, such as Chile, particularly given the post-pandemic food insecurity context. AIM: To assess the use (frequency and doses) of daily recommended supplementation (iron (15-30 mg), folic acid (FA) (400-800 µg/day), and vitamin (VD) (400 IU)) in a sample of Chilean pregnant women. METHODS: In 1, 507 pregnant women selected from public health care registries of the Southeast area of Santiago-Chile, we collected maternal, supplement use, sociodemographic, and nutritional information at the first (<15 weeks), second (24-28 weeks), and third trimesters (32-36 weeks) of gestation by using a researcher administer online questionnaire. RESULTS: The median (IQR) age of women was 29 (25-33) years. Pre-conceptional supplementation was rare (24%), but it reached >93% in the first trimester; thereafter supplement use decreased to 79% in the second and 84% in the third trimesters, particularly in women with lower income (p<0.05), lower education (p<0.05), and with excess weight (p<0.05). Use of iron supplements in the first trimester was rare (<21%) as well as the use of VD supplements across pregnancy (<31%). Most FA (70%) and iron (80%) supplement users, exceeded the recommended daily dose while ~40% of VD users took less than the recommended dose. CONCLUSIONS: In this sample of Chilean women, timely initiation of FA, iron, and VD supplementation was low and doses were not aligned with the recommendations. Strengthening adherence and quality of micronutrient supplementation programs delivered through public primary care could benefit particularly the most vulnerable women.

RESUMEN

Microminerals are necessary for all bodily functions. In animal species, selenium (Se), copper (Cu) and zinc (Zn) all form part of antioxidant enzymes. Micromineral deficiencies, particularly Se, are well recognized in large animal species in Chile. Glutathion peroxidase (GPx) is a widely used biomarker for Se nutritional status and to diagnose Se deficiency in horses. Superoxide dismutase (SOD) is a Cu and Zn-dependant antioxidant enzyme, although it is not commonly used as a proxy for the nutritional status of these minerals. Ceruloplasmin (CP) is used as a biomarker of Cu nutritional status. This study´s objective was to explore correlation between said minerals and biomarkers in adult horses from southern Chile. Se, Cu, Zn, GPx, SOD, and CP were measured in whole blood of a group of 32 adult horses (5-15 years old). Further, a second group of 14 adult horses (5-15 years old) underwent gluteal muscle biopsies to determine Cu, Zn, GPx, and SOD. Correlations were determined by means of Pearson´s r coefficient. Significant correlations were found for blood GPx and Se (r = 0.79), blood GPx and SOD (r = -0.6), muscular GPx and SOD (r = 0.78), and Cu and CP (r = 0.48). These results confirm previously described strong association between blood GPx and Se in horses, validating the former´s use as a diagnostic proxy of Se deficiency in Chilean horses, and suggest significant interactions between GPx and SOD in blood and muscle tissue.

RESUMEN

This paper reflects on the right to health care from the Indigenous research paradigm. We analyze the case of an Aymara wise warmi (woman) who died after the Chilean health care system failed to provide culturally appropriate care. In the wake of her death, our cooperative launched an interdisciplinary and collaborative research project in an effort to file an administrative complaint against the family health center that treated her. We explore the events surrounding her treatment and death, as well as the institutional written response. Our work elucidates the significant differences that exist between institutional and Indigenous perspectives on what constitutes a violation of the right to health care. We demonstrate that in order to establish the existence of such violations, Aymara people are compelled to develop evidence using a naturalistic scientific and legal framework that does not coincide with their ontology. Consequently, some events and violations are not legally recognized as culturally inappropriate health care unless they are viewed through an Indigenous lens. Finally, we reflect on the problem of evidence production, specifically regarding the right to health care. We argue that the fight for the right to health care can benefit from the Indigenous research paradigm-not only for the benefit of Indigenous people but also to provide culturally appropriate care to all people.

RESUMEN

The wild relatives of modern tomato crops are native to South America. These plants occur in habitats as different as the Andes and the Atacama Desert and are, to some degree, all susceptible to fungal pathogens of the genus Alternaria. Alternaria is a large genus. On tomatoes, several species cause early blight, leaf spots and other diseases. We collected Alternaria-like infection lesions from the leaves of eight wild tomato species from Chile and Peru. Using molecular barcoding markers, we characterized the pathogens. The infection lesions were caused predominantly by small-spored species of Alternaria of the section Alternaria, like A. alternata, but also by Stemphylium spp., Alternaria spp. from the section Ulocladioides and other related species. Morphological observations and an infection assay confirmed this. Comparative genetic diversity analyses show a larger diversity in this wild system than in studies of cultivated Solanum species. As A. alternata has been reported to be an increasing problem in cultivated tomatoes, investigating the evolutionary potential of this pathogen is not only interesting to scientists studying wild plant pathosystems. It could also inform crop protection and breeding programs to be aware of potential epidemics caused by species still confined to South America.

RESUMEN

Despite progress on the Millennium and Sustainable Development Goals, significant public health challenges remain to address communicable and non-communicable diseases and health inequities. The Healthier Societies for Healthy Populations initiative convened by WHO's Alliance for Health Policy and Systems Research; the Government of Sweden; and the Wellcome Trust aims to address these complex challenges. One starting point is to build understanding of the characteristics of successful government-led interventions to support healthier populations. To this end, this project explored five purposefully sampled, successful public health initiatives: front-of-package warnings on food labels containing high sugar, sodium or saturated fat (Chile); healthy food initiatives (trans fats, calorie labelling, cap on beverage size; New York); the alcohol sales and transport ban during COVID-19 (South Africa); the Vision Zero road safety initiative (Sweden) and establishment of the Thai Health Promotion Foundation. For each initiative a qualitative, semistructured one-on-one interview with a key leader was conducted, supplemented by a rapid literature scan with input from an information specialist. Thematic analysis of the five interviews and 169 relevant studies across the five examples identified facilitators of success including political leadership, public education, multifaceted approaches, stable funding and planning for opposition. Barriers included industry opposition, the complex nature of public health challenges and poor interagency and multisector co-ordination. Further examples building on this global portfolio will deepen understanding of success factors or failures over time in this critical area.

RESUMEN

BACKGROUND: In June 2016, a comprehensive food policy was implemented in Chile that included front-of-package warning labels on key nutrients of concern (total sugars, added saturated fats, sodium, and calories), child-directed food advertisement bans, and school regulations. The policy was implemented in 3 phases from 2016 to 2019 and the primary objective was to improve children's food environments. This study's objective was to assess changes in child and adolescent intake of key nutrients of concern (total sugars, saturated fats, and sodium) at school after the initial implementation of Chile's Law of Food Labeling and Advertisement. METHODS: Longitudinal study of 349 children from the Food Environment Chilean Cohort (FECHIC) and 294 adolescents from the Growth and Obesity Cohort Study (GOCS). Data were from single 24-hour dietary recalls collected from 2016 to 2019. Fixed-effects models stratified by school, home, and other locations compared nutrient consumption in each year to consumption at the pre-policy 2016 baseline. Nutrient intakes are expressed as percent of total energy. RESULTS: Compared to 2016 (pre-policy), total sugars consumed by children at school decreased 4.5 [-8.0, -0.9] percentage points (pp) and 11.8 [-15.4, -8.3] pp in 2018 and 2019 respectively. In 2019, children's saturated fats and sodium intake at school also decreased (1.1 [-1.9, -0.2] pp and 10.3 [-18.1, -2.5] mg/100 kcal respectively). Likewise, in adolescents, total sugars and saturated fats consumed at school decreased in 2018 (5.3 [-8.4, -2.2] pp and 1.5 [-2.7, -0.3] pp respectively). However, consumption of key nutrients of concern at other locations increased after implementation of the policy. CONCLUSIONS: After initial implementation of Chile's Labeling Law, intake of most key nutrients of concern significantly declined at school. However, we found evidence of compensatory behavior in out-of-school settings. Further research is needed to evaluate what other actions are needed to impact overall diets in the long term both at schools and out of school.

RESUMEN

Beehive derivatives, including honeybee pollen (HBP), have been extensively studied for their beneficial health properties and potential therapeutic use. Its high polyphenol content gives it excellent antioxidant and antibacterial properties. Today its use is limited due to poor organoleptic properties, low solubility, stability, and permeability under physiological conditions. A novel edible multiple W/O/W nanoemulsion (BP-MNE) to encapsulate the HBP extract was designed and optimized to overcome these limitations. The new BP-MNE has a small size (∼100 nm), a zeta potential greater than +30 mV, and efficiently encapsulated phenolic compounds (∼82%). BP-MNE stability was measured under simulated physiological conditions and storage conditions (4 months); in both cases, stability was promoted. The formulation's antioxidant and antibacterial (Streptococcus pyogenes) activity was analyzed, obtaining a higher effect than the non-encapsulated compounds in both cases. In vitro permeability was tested, observing a high permeability of the phenolic compounds when they are nanoencapsulated. With these results, we propose our BP-MNE as an innovative solution to encapsulate complex matrices, such as HBP extract, as a platform to develop functional foods.

RESUMEN

PURPOSE: Latin American reports on genetic cancer risk assessments are scarce. In Chile, current breast cancer (BC) guidelines do not define strategies for germline genetic testing. Our study sought to quantify the disparities in access to genetic testing in Chilean BC patients, according to international standards and their clinical characteristics to explore improvement strategies. METHODS: Retrospective analysis of invasive BC databases including patients treated in a Public Hospital (PH) and in an Academic Private Center (AC) in Santiago, Chile between 2012 and 2021. RESULTS: Of 5438 BC patients, 3955 had enough data for National Comprehensive Cancer Network (NCCN) categorization. From these, 1911 (48.3%) fulfilled NCCN criteria for germline testing, of whom, 300 were tested for germline mutations and 268 with multigene panels. A total of 65 pathogenic variants were found in this subset. As expected, BRCA1/2 mutations were the most frequent (17.7%). Access to genetic testing was higher in AC versus PH (19.6% vs. 10.3%, p = 0.0001). Other variables associated with germline genetic testing were BC diagnosis after 2018, being 45 years old or younger at diagnosis, BC family history (FH), FH of ovarian cancer, non-metastatic disease, and triple-negative subtype. CONCLUSION: In our cohort, 15% of BC patients who met NCCN criteria for germline testing were effectively tested. This percentage was even lower at the PH. Current recommendations encourage universal genetic testing for BC patients; however, our findings suggest that Chile is far from reaching such a goal and national guidelines in this regard are urgently needed. To our knowledge, this is the first study of its kind in Chile and Latin America.

RESUMEN

Mining activities have been a part of the history of Chile since time immemorial, generating pollution and environmental liabilities. Due to the lack of regulation, many tailings are deposited close to rivers or/and on unstable ground, near which towns have been built, generally in locations with no budget for their treatment. This study tested three plant species from Northern and Central Chile to remove total chromium, nickel, and zinc from tailings: Solidago chilensis, Haplopappus foliosus, and Lycium chilense, which complements the few existing studies on heavy metals removal with native or endemic Chilean shrubs. The experiments were conducted ex situ, and the initial and final concentrations of metals were determined in tailings and plants to obtain the removal efficiency, translocation and bioconcentration factors. Among these species, the best performance was obtained using Solidago chilensis, achieving removal efficiencies of 24% for Cr, 19% for Ni, and 17% for Zn, showing the ability to phytostabilize chromium and the higher resistance concerning the toxicity threshold. Haplopappus foliosus and Lycium chilense presented a slight tendency to stabilize chromium. Only Solidago chilensis showed little ability to extract Zn.

RESUMEN

AIM: To evaluate the in vitro and in vivo antifungal capability of diverse compost teas of endemic Chilean flora inoculated with a consortium of fungal strains of Trichoderma spp. (biocontrol agent) against three important phytopathogens: Botrytis cinerea, Fusarium oxysporum, andLasiodiplodia theobromae. METHODS AND RESULTS: Compost teas were obtained from the endemic flora of Chile (Azara celastrina, Citronella mucronate, Cryptocarya alba, Peumus boldus, and Quillaja saponaria). Eleven Trichoderma strains were isolated, and antagonism tests were performed to develop fungal consortiums with biocontrol properties. The biocontrol effect of compost teas inoculated with Trichoderma consortia was also analyzed. The results showed that the teas possess antifungal activity against B. cinerea and F. oxysporum and, to a lower degree, against L. theobromae. In vitro tests showed that Trichoderma consortiums improved the suppressive effect against B. cinerea (94-97%), F. oxysporum (89-92%), and L. theobromae (51-73%). Peumus boldus tea showed the highest suppressive effect against the plant pathogen L. theobromae. In addition, the in vivo assay showed that tomato plants treated only with Trichoderma or compost tea did not show differences in height with regard to control plants. However, when these two treatments were combined, the best performance in plant height and protection against pathogens was observed. CONCLUSIONS: This study indicates that the addition of a consortium of Trichoderma strains with intra- and interspecific incompatibilities significantly improves the inhibitory effect of compost teas in in vitro tests against the plant pathogenic fungi, while in vivo it enhances tomato plant growth and reduces plant disease symptoms.

Despite its worldwide relevance as an invasive plant, there are few studies on Ulex europaeus (gorse) and its allelopathic activity is almost unexplored. The allelochemical profile of gorse was analysed through methanolic extract of pods and roots, and its phytotoxic effects on Lactuca sativa germination. The methanolic extract of pods had no effect in germination, while extract of roots resulted in a U-shaped dose-response curve: reducing the germination at concentration 0.5 mg mL-1. GC-MS analysis detected compounds with proven antimicrobial and antioxidant activities in the pods and cytotoxic compounds in the roots, which could explain the bioassay results. The quinolizidine alkaloids (QAs) composition was evaluated to predict possible biological functions. It showed the presence of QAs in gorse that are absent in their native range, indicating broad defense strategies against bacteria, fungi, plants, and insects in the Chilean ecosystem. This could explain the superiority of gorse in the invaded areas.

RESUMEN

Spirituality and religiousness are important factors for adolescents wellbeing. Little is known about the mechanisms underlying the positive relationship between spirituality as well as religiousness and subjective wellbeing. This study aimed to verify, whether, in a sample of Chilean students, religiousness is indirectly related to hope through spiritual experiences, and whether spiritual experiences are indirectly related to subjective wellbeing via hope. The sample consisted of 177 Chilean students and the following measures were applied: the Daily Spiritual Experiences Scale, the Herth Hope Index, the Satisfaction With Life Scale, the Positive and Negative Affect Schedule, and one item measuring the frequencies of prayer and Mass attendance. According to obtained results religiousness was indirectly, positively related to hope through spiritual experiences. In turn spiritual experiences were indirectly, positively related to subjective wellbeing through hope. Conducted research confirmed the beneficial role of religious practices, spiritual experiences, and hope for Chilean students' subjective wellbeing and the presence of mechanisms underlying the relationships between religiousness as well as spirituality and subjective wellbeing.
